Given numbers are 978,988,309,263
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,988,309,263 is 13087562748.
Find LCM of 978,988,309,263 with Prime Factorization
| 2 | 978, 988, 309, 263 |
| 3 | 489, 494, 309, 263 |
| 163, 494, 103, 263 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 494 x 103 x 263 = 13087562748
Therefore, the lowest common multiple of 978,988,309,263 is 13087562748.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
978 x 988 x 309 x 263 = 78525376488
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
978 : 1, 2, 3, 6, 163, 326, 489, 978
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
309 : 1, 3, 103, 309
263 : 1, 263
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,988,309,263, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
988:2x 2x 13x 19
309:3x 103
263:263
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 78525376488/(1x6)
LCM = 78525376488/6
LCM = 13087562748
Thus, we can understand that the LCM of 978,988,309,263 is 13087562748.
